A neuron star has a mass of 2.0 x 10^30 kg (about the mass of our sun) and a radius of 5.0 x 10^3 m (about half the height of a good-sized mountain). suppose an object falls from rest near the surface of such a star. how fast would this object be moving after it had fallen a distance of 0.010 m? (assume that the gravitational force is constant over the distance of the fall and that the star is not rotating.)
